Backend (the "logs arrive every ~5s / pipe clogged" bug):
- dockerLocalProxy.ServeHTTP streamed the docker socket response via
io.Copy, which buffers ~2KB into the ResponseWriter and only flushes
when full or on handler return. Low-throughput streaming endpoints
(container logs follow=1, events, stats, attach) therefore arrived in
multi-second batches. Stream manually and Flush() after each chunk so
they are delivered live. Behaviour is otherwise identical to io.Copy
(full-write contract, EOF handling, Debug error logging); hijacked
attach/exec go through a separate websocket handler, unaffected.
- NewSingleHostReverseProxyWithHostHeader: set FlushInterval = -1 so the
remote-endpoint path streams live too.
Frontend (maintainer UI asks):
- Remove the line-selection mechanic entirely (Copy-selected-lines and
Unselect buttons, selectLine/copySelection/clearSelection, selectedLines
state, line_selected highlight): selecting/copying is mouse-native. Copy
(all visible) and Download stay.
- Rename the unclear "Fetch" since-selector label to "Since".
- Move the settings controls into the widget header (rd-widget-header
default transclude slot) so they share one row with the "Log viewer
settings" title, reclaiming vertical space for the log pane.

Per maintainer request: remove the 'Auto-refresh logs' toggle entirely — logs are
now always collected (container always streams, service/task always poll). Drops
state.logCollection and its whole cascade (handleLogsCollectionChange, the
logCollectionChange binding, changeLogCollection in all three view controllers,
the log-collection-change attribute) and the now-dead manual flush-on-pause
machinery (pausedFlushCount / removeTailLines / the flush branch); pauseStream is
kept for $destroy/reconnect teardown, and the stream/poll start unconditionally.
Collapse the seven stacked settings rows into a single compact flex row
(wrap-lines, timestamps, fetch, lines, search, actions) — bindings unchanged.

Replace the 3s $interval polling of container logs with a live HTTP
stream, and stop re-writing already-rendered lines (fixes selection bug).
- streamContainerLogs (containers.service.ts): fetch + ReadableStream
reader with follow=1, same-origin credentials:'include' (httpOnly JWT
cookie; CSRF only guards mutations), agent-target / manager-operation
headers replicated for Agent/Edge, AbortSignal-driven lifetime.
- containerLogsController: stream instead of poll; append parsed lines
into the buffer (push, never replace), cap at 5000 lines trimming from
the head; AbortController on pause/destroy/param-change; reconnect with
3s backoff resuming from `since` (dropping tail) on stream end/error;
Live toggle pauses/resumes the stream; tail/since/timestamps changes
restart the stream.
- log-viewer: `track by log.id` (was $index), filtering moved out of the
template into the controller (applyFilter via $watchCollection), removed
inert force-glue, decoupled auto-scroll from log collection, relabelled
"Auto-refresh logs" -> "Live logs", clearer empty states.
Backend unchanged (logs already stream transparently through the Docker
proxy). Shared task/service log views keep working via the new id'd lines.

* chore(log-viewer): add the ability to use`since` parameter #1942https://github.com/portainer/portainer/issues/1942#issuecomment-430246378
* chore(log-viewer): change lineCount to 100 #1942https://github.com/portainer/portainer/issues/1942#issuecomment-430246378
* fix(log-viewer): js syntax typo for `;` and `'`
forget to lint the code, reported by codeclimate
* fix(log-viewer): use mementjs to format timestamp
1. use moment lib instead of define a function in filter.js(not the right place for this function, removed)
2. set sinceTimestamp init value to `24 hours ago`, as we just need to focus on the relative latest logs after the log-viewer loading, not all the logs(to speedup the process)
3. use moment().unix() to convert the `sinceTimestamp` to local unix timestamp(not utc)
* chore(log-viewer): add the ability to select the datetime for `since`
* chore(log-viewer): add the ability to fetch logs from specific time
* feat(log-viewer): use only one switch to manage collection/autoscroll
* feat(log-viewer): add the ability to clear selection
* style(log-viewer): update unselect button design
